SPENCER C. CARY, OF BALDVIN, NEW YORK.

B O X S T RA P SPECIFICATION forming part of Letters Patent No. 403,24*?, dated May 14, 1889.

Application filed January 3l, 1889. Serial No. 298,173. (No model.)

To a/ZZ whom it 11mg/ concern:

Be it known that I, SPENCER C. CARY, of Baldwin, county of Queens, State of New York, a citizen of the United States, have invented certain new and useful Improvements in Reels for Box-Straps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to metal straps for packing-boxes; and it consists in a reel for such box-straps composed of the parts and devices hereinafter particularly described, and constructed and arranged to operate to hold coiled upon it the metal box-strap, and to permit the uncoiling thereof therefrom, as hereinafter set forth.

Figure l is a side elevation of a reel containing my invention and having' a metal boxstrap coiled thereon. Fig. 2 isa vertical central section of the reel and coiled strap thereon on line .fr oo, Fig. l, and showing the reel mounted upon a fixed support. Fig. 3 is an edge view of a modiiied form of the reel with a strap coiled thereon and showing the same mounted to a fixed support.

In constituting a reel for a coil of metal box-strap I employ the following devices, namely:

C is a spool j ournaled to revolve freely upon a shaft, c, in a frame, D. This frame D consists of two arms, d and d', which extend from the shaft c, parallel to each other, to a point somewhat beyond the line of the circumference of the intended coil of strap upon the spool, and which are united together at their extended or outer ends, as shown at d2. In each said outer end is formed an opening, d3, the openings registering with each other in both said ends, as shown. The said frameD may be conveniently formed of a metal band bent upon itself iiatwise about midway its ends to constitute the two parallel arms d and d', and the shaft c may be seated in the free ends of the band, the openings d3 being punched in the band near its bend, as shown. The shaft c is a hollow shaft, as shown, and the arms d and d are sufciently distant from each other to permit the spool C to revolve on its shaft between them, as shown.

A box-strap of metal, as shown at E, Figs.

3 and '4, is coiled fiatwise on the spool C, and when the coil is complete, as described,a pin or nail, f, may be forced into the corresponding openings, cl3, in the outer end of the frame, so that the end of the coil may rest against or be turned backward over said pin, as shown in Fig. l, and the resiliency or spring-like action or tendency of the entire coil acts to press the strap end against said pin snugly and hold the coil firmly in position on the spool and in the frame. Thus coiled and held the strap is adapted for transportation.

It is designed and intended that the coiled strap in the described frame-reel shall be mounted, atthe place where it is severed into definite desired lengths for sale or usa-upon some convenient support, as the side of a shopcounter or a post. To accomplish this the reel is mounted upon the supportnsuch as is shown at E-by driving anail or pin, f', through the hollow shaft c and into the support, and driving a nail or pin, f, through the corresponding openings, d3, in the frame and into the support, as shown. By this means the framed reel is held firmly :in position on the support and the spool and coil are free to revolve on the shaft c of the former in unreeling the strap. Furthermore, the fastening-nails, together with the hollow shaft c, may be made to serve to draw or hold the sides d d of the frame closely to the .edges of the strap-coil, so as to hold the strap from uncoiling without the exertion of force by the operator on the free end of the coil. The strap-coil will also, by its resiliency as it is uncoiled, when not held by the frameside d d', be carried against and held by the pin f and prevented from unreeling.

The frame D may be made with its arms (Z and d to reach diametrically across the spool C and to extend to the circumference of the strap-coil on opposite sides thereof, the outer ends of the arms being united beyond the periphery of the coil, as shown in Fig. 3. This may be conveniently effected by having the metal band which constitutes the frame extend continuously across the spool and strapcoil thereon on one side, and then bending the band upon itself at the opposite edges of the coil and across said edges, and bringing the ends to and lapping and holding them at and by the shaft c, as shown in Fig.' 3. When IOO the frame D is made in this forni, corresponding apertures, d", maybe made in the ends of the arms CZ and d opposite to ends thereof in which are the described silnilar apertures, d3, and the reel may be fastened to its support, as shown in Fig'. 3, by nails driven through the said apertures d3 and d", and the shaft e need not be hollow. The frame in this forni will serve to hold and protect the strap- Coil on both sides of the spool, and to sustain the reel and duly confine the strap'eoil While unreeling` when the reel is attached. to its support.

That l claim as lny invention, and desire to secure by Letters Patent, is-

1. A reel for inetal box-straps, consisting oi a spool, C, adapted to have the meta-l strap coiled upon it, a hollow axle, o, upon which said spool is jonrnaled to turn freely, and by which the reel may be secured upon a support, and a frame, D, composed of the parallel arms d and d', in which the said axle is mounted, and which extend radially therefrom alongside of and beyond the rim of said spool, as described, and are united at their outer ends` and therein have the Corresponding openings, d, adapted to receive a fasteningpin, substantiallyas and for the purpose specified.

2. A reel for meta-l box-straps,Consisting of a spool7 C, adapted to have the metal strap @oiled upon it, an axle, 0, upon which said spool is journaled, and a frame, D, composed of parallel arnis d and d', in which said axle is mounted7 and which extend diametrieally across said spool and reach in opposite directions beyond the rini thereof, as described, and are united at their outer ends, and there in have the respective corresponding openings, d3 and il, adapted to receive fasteningpins, substantially as and for the purpose set forth.
